Filed Mar. 16, 1959, Ser. No. 799,549 3 Claims. (Cl. 126-344) 'I'he present invention relates to a portable and collapsible water heater and particularly one to be used for camping and the like.

The primary object of the invention is to provide a portable water heater that can be used in connection with a campfire or camp stove for heating of water.

A further object of the invention is to provide a collapsible water heater that can be folded into a small package while not in use. The present water heater in no way interferes with cooking utensils heated by the camp tire or camp stove.

A still further object of the invention is to provide a collapsible Water heater that is strong and lightweight, and requires a minimum of space for storage.

Other objects and advantages will become apparent in the following specication when considered in light of the attached drawings, in which:

FIGURE 1 is a side view of the invention with parts broken away for convenience of illustration;

FIGURE 2 is a plan view of the structure shown in FIGURE 1 with parts broken away for convenience of illustration;

FIGURE 3 is a side view showing the device in collapsed folded position;

FIGURE 4 is a rear view of the invention in folded position, showing the heating coil in storage position;

FIGURE 6 is a fragmentary enlarged sectional view taken on line 7-7 of FIGURE 2, looking in the direction of the arrows;

FIGURE 7 is a fragmentary detail view looking into the upper edge of the bag, illustrating how the bag is supported; and

FIGURE 8 is a perspective View of a modified heating coil used in connection with camp stoves and the like.

Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several iigures, the reference character H indicates generally a portable collapsible water heater constructed in accordance with the invention. The heater H includes a relatively rigid vertically disposed wall 10 having a right angled foot 11 integrally formed on its lower edge, providing a base and a partial end wall. A ledge 12 is integrally formed on the upper edge of the wall 10 parallel to the foot 11. A second relatively rigid plate 13 is secured to the ledge 12 by hinges 14 and extends in a normally horizontal plane towards a depending flange 15 depending from its opposite edge.

Supported by the vertical wall 10 is a bag 16. The bag 16 includes relatively rigid upper and lower rings 17 yand 18. The upper ring 17 is pivotally connected to the wall 10 by an I-bolt 19, as best illustrated in FIGURE 6. Suspended from the n'ng 17 is a exible shell 20. The lower end of the shell 20 is secured to a relatively rigid n'ng 18 and has a closed bottom 22.

Pivotally connected to the wall 10 are struts 23 and 24. 'Ihe upper end 25 of the strut 24 engages the loop 26 forming part of the upper ring 17, one strut 24 being located on either side of the bag 16. The upper ring 17 is maintained in a horizontal position together with the iiexible shell 20 and the lower ring 18 by the struts 24. The lower ends 27 of the struts 23 engage the loops 28 forming part of the lower ring 18 to support the whole assembly in vertical position relative to the ground surface.

Pipe fittings 29 and 30 pass through the wall 10 and through the side of the tlexible shell 20. The fittings 29, 30 receive the opposite ends of the coil 31. 'I'he coil 31 is to be heated over a camp lire 32, as best illustrated in FIGURE 1. Due to the vertical arrangement of the coil 31, heated water will be caused to llow into the upper fitting 29 ofthe shell 20 with the cooler water coming out the fitting 30 and being heated over the tire and circulated.

FIGURE 8 illustrates a modified coil 31A that can be used to encircle a camp stove (not shown).

In order to fold the portable and collapsible water heater H, the ends 25 and 27 of the struts 23 and 24 are removed from the loops or eyes 26 and 28. 'I'his permits the bag 16 to be collapsed in the following manner.

The ring 17 will pivot within the I-bolt 19 allowing the ring 17 to fold toward the supporting wall 10 and also the lower ring 18 can be folded towards the wall 10 at the same time, folding the exible shell 20 towards the wall 10, as best illustrated in FIGURE 3.

The horizontally disposed plate 13 can then be folded down closing the folded bag 16 and supporting struts 23, 24 between the Wall 10 yand the plate 13. At the same time the ttings 29 and 30 are loosened, allowing the coil 31 to be removed and clipped into the clips 33, which are iixedly secured to the basic Wall 10, as best illustrated in FIGURES 3 and 4.

In order to move the assembled device from place to place, after the horizontally disposed plate 13 is hinged rearwardly, the operator grasps the struts 23 or 24 for carrying the same from place to place.

Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claims.

What is claimed is:

1. A portable water heater for use with camp fires, cook stoves and the like comprising a generally rectangular panel, a foot integrally formed on one end of said panel extending perpendicularly therefrom, a ledge integrally formed on the opposite end of said panel and extending generally parallel to said foot, a second panel hingedly secured to said ledge and foldable from a position aligned with said ledge to a position spaced from and parallel to said rst named panel, a tlexible shell, a pair of rings pivotally secured to said rst named panel in spaced apart parallel relation supporting the opposite ends of said shell, a plurality of struts releasably seeming said rings in spaced parallel relation and a tubular coil supported on said first named panel with the opposite ends thereof communicating with said shell whereby water stored in said shell will be heated in said coil with said coil positioned in Contact relation with a source of heat.

2. A portable water heater for use with camp iires, cook stoves and the like comprising a panel, a foot formed on one end of said panel extending perpendicularly therefrom, a ledge formed on the opposite end of said panel and extending generally parallel to said foot, a second panel hingedly secured to said ledge and foldable from a position aligned with said ledge to ya position spaced from and parallel to said rst named panel, a llexible shell, a pair of supports pivotally secured to said rst named panel in spaced apart parallel relation supporting the opposite ends of said shell, a plurality of struts releasably securing said supports in spaced parallel relation and a tubular coil supported on said first named panel with the opposite ends thereof communicating with said shell whereby Water stored in said shell will be heatedv in said coil with said coil positioned in contact relation with a source of heat.

Y 3. The invention as set forth in claim 2 wherein said 'second'rpanelrha's a depending ange, said ange over- 5 lapping said foot when said panels are in collapsed posirtion, and said shell, said struts and said supports then contained Within the confines of said collapsed panels.
